Solids - Melting and Boiling Temperatures - Melting and boiling temperatures of some products.Mach Number - An introduction to the Mach Number.Liquids - Speed of Sound - Speed of sound in common fluids like water, glycerol, kerosene and more.Gases - Speed of Sound - Speed of sound in some gases at zero degrees Celsius and atmospheric pressure.Temperature - Speed of sound in air at standard atmospheric pressure with temperatures ranging -40 to 1000 oC (-40 to 1500 oF) - Imperial and SI Units. Acoustics - Room acoustics and acoustic properties, decibel A, B and C, Noise Rating (NR) curves, sound transmission, sound pressure, sound intensity and sound attenuation.Velocity is vector quantity with direction. Variability in the speed of sound relates to the variability of modulus of elasticity and density. The speed of sound across the grain is about one-fifth to one-third of the longitudinal value. There is no recognized independent effect of species of wood on the speed of sound. In wood the speed of sound varies with grain direction because the transverse modulus of elasticity is as little as 1/20 the longitudinal value. speed of extensional waves along a rod (with diameter much smaller than the wavelength).
speed of shear waves in infinite elements.speed of longitudinal waves in infinite elements (elements much larger than the wavelength of the sound).In an isotropic solid sound speed is characterized by In a liquid or gas only one speed is required.
